A Study on the Application of Extended Care Based on the Biopsychosocial Medicine Model in People with Abnormal Tumor Markers on Physical Examination

The purpose of this study was to explore the value of extended care based on a biopsychosocial medicine model in patients with abnormal tumor markers on physical examination. One hundred and fifty-two cases with abnormal primary screening tumor markers who were examined in our medical examination center between January 2020 and January 2022 were selected as the subjects of this study and divided into intervention and control groups according to the random number table method, with 76 cases in each group. The control group was given the usual extended care intervention and the intervention group was given the extended care intervention based on the biopsychosocial medicine model. The compliance rates of regular follow-up, reasonable diet, appropriate exercise, and regular rest were compared between the two groups. After the intervention, the disease-related knowledge score in the intervention group was higher than that in the control group (P < 0.05). The compliance rates of regular return visits, reasonable diet, appropriate exercise, and regular routines in the intervention group were higher than those in the control group (P < 0.05). After the intervention, the scores of psychological states such as anxiety, depression, and post-traumatic growth in the intervention group were better than those in the control group (P < 0.05). After the intervention, the total scores of objective support, subjective support, support utilization, and social support in the intervention group were higher than those in the control group (P < 0.05). After the intervention, the intervention group had higher positive coping scores and lower negative coping scores than the control group (P < 0.05). Continuing care based on the biopsychosocial model of medicine is effective in people with abnormal tumor markers on medical screening. It can improve the knowledge about the disease, increase the compliance rate, improve negative emotions, psychological status, and social support, and promote a more positive way of responding.


Introduction
With the change of modern people's living habits and diet structure, the incidence of malignant tumors is increasing year by year. According to statistics, the number of new cases of malignant tumors in China is as high as 4.57 million and the number of deaths is as high as 3 million, which are ranked the foremost in the world [1]. Monitoring tumor marker levels during regular medical checkups is currently an effective way to prevent and screen for tumors, and in the course of clinical application, some medical checkups can screen positive for tumor markers. However, not all patients have the correct knowledge of the results after the medical report is issued [2]. In addition, the physical examination population lacks timely and effective follow-up and social psychological intervention after leaving the hospital, which makes some physical examination people unbalanced due to abnormal examination results, unable to review or receive treatment on time, resulting in delayed illness [3]. It has been reported that the implementation of extended care interventions can help to increase the follow-up rate of patients with abnormal tumor markers and improve their psychological state [4]. e biopsychosocial model of care intervention is a new approach to care based on a modern medical model that takes into account the physical, psychological, and social factors of the care recipient to provide the care they need [5]. At present, there are few studies on the continuation of the biopsychosocial model of nursing intervention in patients with tumor marker abnormalities in medical checkups. Based on this, this study implemented the continuation of the biopsychosocial model of nursing care in patients with tumor marker abnormalities admitted to our medical checkup center in the past two years to observe its application effect.

2.1.
Patients. 152 patients with abnormal tumor markers who were admitted to our physical examination center from January 2020 to January 2022 were selected as the subjects of this study and divided into the intervention group and control group according to the random number table, with 76 cases in each group. ere was no significant statistical difference (P > 0.05) between the two groups in terms of gender, age, education, and other general data, which were comparable (Table 1). is study was approved by the Ethics Committee of Fenyang Hospital Shanxi Province. Signed written informed consents were obtained from all participants before the study. e inclusion criteria was as follows: (1) all of them were found to be positive for serum carcinoembryonic antigen, alpha-fetoprotein, glycoprotein antigen, and other tumor markers for the first time; (2) patients aged 18 to 75 years old; (3) the clinical data were complete, informed, and agreed to this study. e exclusion criteria was as follows: (1) patients who had been diagnosed with malignant tumor; (2) patients with blood system diseases, autoimmune diseases, or acute and chronic infectious diseases; (3) patients with mental disorders, unable to communicate normally, and difficult to understand the contents of care; (4) patients who could not cooperate to complete this follow-up.

Methods.
In the control group, routine continuity of care services were given, physical examination reports were provided to the examinee, the examinee was suggested to maintain a scientific diet and lifestyle habits, and the examinee was advised to come to the hospital on time for follow-up examinations, and was informed of the time, items, and significance of the follow-up examinations. In the intervention group, continuing care interventions based on the biopsychosocial model were as follows: (1) establishment of a continuing care intervention team based on the biopsychosocial model. 4 highly qualified nurses form the intervention team and are trained in the biopsychosocial model before providing care. A health profile was created, taking into account the patient's own situation, and a continuity of care intervention plan based on the biopsychosocial model was developed. (2) Follow-up: team members used telephone, WeChat, and family visits to follow-up with patients who had abnormal tumor markers. During the follow-up visits, they repeatedly provided health education to the patients, informing them about the test results, precautions, and the role of retesting. e pathology information was collated into a personal health file and centrally fed back to the doctor. At the same time, during the follow-up visit, the team should understand the health checker's living habits, work and rest patterns, and dietary preferences, and suggested that the health checker should correct any unreasonable points, so as to maintain a reasonable diet, work and rest, and sleep, and develop healthy living habits. (3) Emotional support: the team should establish good communication and trust with the patient through several follow-up visits, listen to the patient's true thoughts and feelings, grasp the patient's emotional and psychological state, help the patient establish a correct view of tumor marker testing, eliminate the patient's tension and fear of abnormal results, help the patient relieve anxiety and depression and other psychological burdens, and calm the patient's emotions. Appropriately, the team should also help the patients to relieve their anxiety, depression, and other psychological burdens, reassure their emotions, tell them about successful and warning cases, inform them of the importance of early screening, encourage them to come to the hospital for follow-up examinations on time in order to exclude or confirm the diagnosis of tumors at an early stage, and help them to build up their confidence by giving them sufficient emotional support and to meet the follow-up examinations with a positive attitude. (4) Guidance on follow-up examinations: members of the intervention team helped those who had previously been followed up to make appointments for follow-up examinations, and reminded them again by phone one day before the follow-up examination time. e reminders included precautions before the follow-up examination, the procedure of the follow-up examination, the contents of the follow-up examination, and the time of the follow-up examination, to ensure that the examinee completed the follow-up examination smoothly and to avoid other factors interfering with the results. Physical examinees in both groups continued to intervene for 45 days.

Observation Index.
Disease-related knowledge: a selfmade questionnaire on disease-related knowledge was developed with reference to the literature [6], which contained the significance of tumor marker detection, the significance of positive results, examination precautions, the significance of return visit, and the importance of return visit, etc., with a total score of 100 points, indicating that the physical examinees had a better disease-related cognition level. Compliance behavior [7]: after the intervention, the compliance behavior such as regular return visit, reasonable diet, appropriate exercise, and regular routines of the two groups of physical examinees were evaluated, respectively, and the evaluation dimensions were complete compliance, partial compliance, and complete noncompliance, those who met complete and partial compliance were regarded as compliance, and those who met complete noncompliance were regarded as noncompliance, and the compliance rate of the two groups of physical examinees was compared. Psychological state: before and after the intervention, the mental state of the two groups of physical examination subjects was evaluated using the Hospital Anxiety and Depression (HAD) Scale [8] and the Chinese version of the Chinese-Posttraumatic Growth Inventory (C-PTGI) [9]. e HAD scale contains two parts: anxiety subscale and depression subscale, with 7 items in each suitable. e total score is 9 points, 0∼8 points without anxiety and depression symptoms, 9∼21 points with anxiety and depression symptoms, representing more severe degree of anxiety and depression of the physical examination subjects. ere are a total of 20 C-PTGI scales, including five dimensions: life perception, personal strength, new possibility, relationship with others, and self-transformation. A six-level scoring system of 0, 1, 2, 3, 4, and 5 is used, with a total score of 100 points, representing more physical examinee grows after trauma. Social support: before and after the intervention, the social support rating scale (SSRS) [10] was used to evaluate the social support of the subjects in the two groups. e SSRS scale had 10 items, including three parts: objective support (2, 6, 7 items), subjective support (1, 3, 4, 5 items), and social support utilization (8, 9, 10 items). e items 1-5 and 8-10 were scored with 1, 2, 3, and 4 items. e items 6 and 7 were scored as 0 point for "no source." ere were several sources to count. e total score was the sum of the scores of each part. e score represented that the social support of the subjects was better. Coping style: before and after the intervention, the trait coping style questionnaire (TCSQ) [11] was used to evaluate the coping status of the physical examinees in the two groups, with a total of 20 items of TCSQ questionnaire, including two major parts: positive coping and negative coping. e five-level scoring system was used. A higher positive response score means that the examinee was more positive and a higher negative response score means that the examinee was more negative.

Statistical Analysis.
e Statistical Product and Service Solutions (SPSS) 22.0 software (IBM, Armonk, NY, USA) was applied for processing and analysis. Measurement data were expressed as (x ± s) by using the t-test, and the count data were expressed as percentages by using the chi-square test. P < 0.05 was considered a statistically significant difference.

Disease-Related Knowledge Scores between the Two Groups.
ere was no significant difference in disease-related knowledge scores between the two groups before intervention (P > 0.05), and the scores in the intervention group were higher than those in the control group after intervention (P < 0.05), as shown in Table 2.

Compliance Behavior between the Two Groups.
e compliance rates of physical examinees in the intervention group such as regular return visits, reasonable diet, appropriate exercise, and regular routines were higher than those in the control group (P < 0.05) ( Table 3).

Psychological Status between the Two Groups.
ere was no significant difference in the scores of psychological status such as anxiety, depression, and post-traumatic growth between the two groups before intervention (P > 0.05), and the scores of psychological status such as anxiety, depression, and post-traumatic growth in the intervention group were better than those in the control group after intervention (P < 0.05) ( Table 4).

Social Support between the Two Groups.
ere was no significant difference in objective support, subjective support, support utilization, and total social support score between the two groups before the intervention (P > 0.05), and the objective support, subjective support, support utilization, and total social support score in the intervention group were higher than those in the control group after the intervention (P < 0.05) ( Table 5).

Coping Style Scores between the Two Groups.
ere was no significant difference in positive coping and negative coping scores between the two groups before the   intervention (P > 0.05), and the positive coping score of the intervention group was higher than that of the control group and the negative coping score was lower than that of the control group after the intervention (P < 0.05) ( Table 6).

Discussion
With the rapid increase in the incidence of malignant tumors in recent years, tumor marker tests such as carcinoembryonic antigen, alpha-fetoprotein, and glycoprotein antigen have become a routine part of medical check-ups for residents, and are important for the early detection and treatment of malignant tumours [12]. When the examination results of tumor markers are abnormal, it suggests the possibility of cancer, and timely and effective return visit is required to further rule out or diagnose cancer. However, in actual clinical practice, some medical examiners may lack knowledge about the disease, resulting in anxiety, depression, and panic, and thus avoiding follow-up consultations [13], and the lack of effective extended care interventions in hospitals may delay the condition and cause the examiners to miss the best time for treatment, which is not conducive to personal, family, and social harmony and stability [14].
In this study, routine continuous nursing was used as a control, and continuous nursing based on biopsychosocial medical model was used to provide nursing services for physical examination patients in the intervention group. e results showed that the compliance rate of disease-related knowledge score, regular return visit, reasonable diet, appropriate exercise, and regular routines of physical examination patients in the intervention group was higher than that in the control group (P < 0.05), indicating that continuous nursing based on biopsychosocial medical model could improve disease-related knowledge and compliance behavior of patients with abnormal tumor markers in physical examination, promote their return visit on time, and maintain healthy living habits.
ose with abnormal tumor markers in physical examination do not understand the meaning of test results due to their lack of understanding of disease-related knowledge, or excessively interpret test results, resulting in significant changes in their psychological status, easy self-abandonment, and development of bad living habits and dietary habits, and some physical examinees may also experience insomnia due to negative emotional distress [15,16]. Continuing nursing based on the biopsychosocial medical model ensures that the physical examinees fully understand and master disease-related knowledge by establishing a nursing group, strengthening the communication between the group members and the physical examinees, and conducting health education oneon-one to the physical examinees, so that they can better cooperate to adjust bad living habits and go to the hospital for return visits in a timely manner [17]. erefore, physical examinees in the intervention group had higher diseaserelated knowledge scores and compliance rates than those in the normal group. e results of this study also found that the intervention group was superior to the control group in the scores of psychological states such as anxiety, depression, and posttraumatic growth (P < 0.05), and the intervention group had higher objective support, subjective support, support utilization, and total score of social support compared with the control group (P < 0.05). After the intervention, the intervention group had higher positive coping scores and lower negative coping scores than the control group (P < 0.05). It is shown that continuous care based on the biopsychosocial medical model can effectively eliminate negative emotions of physical examinees, improve social support, and help them face return visits in an active coping style. When physical examinees get abnormal results, their emotions are greatly affected due to their lack of relevant knowledge, and most physical examinees may experience adverse psychological states such as depressed mood, anxiety, and depression [18]; have a negative attitude towards return visits; and are difficult to actively cooperate to complete further examinations [19]. e members of the  Contrast Media & Molecular Imaging continuous nursing group based on the biopsychosocial medical model establish one-on-one communication with the physical examinees by telephone follow-up, follow-up, and family visit to improve the disease cognition of the physical examinees while more clearly understanding the mental stress and worry points they face. e members of the nursing intervention group give psychological counseling according to the physical examinees' own conditions [20], improve social support and their own confidence with the help of their families, encourage the physical examinees to face return visits and possible treatment with a positive attitude, promote their post-traumatic growth, and improve their psychological status as a whole [21]. is article still has several limitations. For example, this study was only conducted on patients with positive tumor markers, and patients diagnosed at a later stage were not followed up again. Besides, the sample size included in this study was small and this study was a single-center study.

Conclusion
In summary, the application effect of continuous nursing based on biopsychosocial medical model in patients with abnormal tumor markers in physical examination is significant, which can effectively enhance the disease-related knowledge of physical examination patients, improve the compliance rate, eliminate negative emotions, improve psychological status and social support, and promote them to establish a positive coping style.
